本文利用从地震数据中提取的主振幅参数,通过与钻井岩性参数相关拟合分析,排除地震调谐影响,确定地震数据中所包含的岩性信息,结合钻井沉积相、测井相研究成果和区域沉积特征,把地震主参数有效地转化为沉积相,实现了从地震角度研究古沉积环境,并在此基础上确定有利的储层分布区,经后期钻探获得高产油气流证实,该方法的沉积相划分结果是准确的,从而为地震资料的地质应用提供了一个新的方法,为沉积微相的研究提供了一种新的手段。
In this paper, the main amplitude parameters extracted from the seismic data are used to determine the lithological information contained in the seismic data by fitting and analyzing the correlation with the drilling lithology parameters, and combining with the research results of drilling facies and logging facies and Regional sedimentary characteristics of the main seismic parameters effectively converted into sedimentary facies, from the seismic point of view of ancient sedimentary environment, and on this basis to determine the favorable distribution of the reservoir, after drilling to obtain high-yield oil and gas confirmed that the method of The result of sedimentary facies division is accurate, which provides a new method for geological application of seismic data and provides a new method for the study of sedimentary microfacies.
